+## [5.4.1](https://github.com/vmihailenco/msgpack/compare/v5.4.0...v5.4.1) (2023-10-26)
+
+
+### Bug Fixes
+
+* **reflect:** not assignable to type ([edeaedd](https://github.com/vmihailenco/msgpack/commit/edeaeddb2d51868df8c6ff2d8a218b527aeaf5fd))
+
+
+
+# [5.4.0](https://github.com/vmihailenco/msgpack/compare/v5.3.6...v5.4.0) (2023-10-01)
+
+
+
+## [5.3.6](https://github.com/vmihailenco/msgpack/compare/v5.3.5...v5.3.6) (2023-10-01)
+
+
+### Features
+
+* allow overwriting time.Time parsing from extID 13 (for NodeJS Date) ([9a6b73b](https://github.com/vmihailenco/msgpack/commit/9a6b73b3588fd962d568715f4375e24b089f7066))
+* apply omitEmptyFlag to empty structs ([e5f8d03](https://github.com/vmihailenco/msgpack/commit/e5f8d03c0a1dd9cc571d648cd610305139078de5))
+* support sorted keys for map[string]bool ([690c1fa](https://github.com/vmihailenco/msgpack/commit/690c1fab9814fab4842295ea986111f49850d9a4))
+
+
+
+## [5.3.5](https://github.com/vmihailenco/msgpack/compare/v5.3.4...v5.3.5) (2021-10-22)
+
+- Allow decoding `nil` code as boolean false.
+
+## v5
+
+### Added
+
+- `DecodeMap` is split into `DecodeMap`, `DecodeTypedMap`, and `DecodeUntypedMap`.
+- New msgpack extensions API.
+
+### Changed
+
+- `Reset*` functions also reset flags.
+- `SetMapDecodeFunc` is renamed to `SetMapDecoder`.
+- `StructAsArray` is renamed to `UseArrayEncodedStructs`.
+- `SortMapKeys` is renamed to `SetSortMapKeys`.
+
+### Removed
+
+- `UseJSONTag` is removed. Use `SetCustomStructTag("json")` instead.
+
+## v4
+
+- Encode, Decode, Marshal, and Unmarshal are changed to accept single argument. EncodeMulti and
+  DecodeMulti are added as replacement.
+- Added EncodeInt8/16/32/64 and EncodeUint8/16/32/64.
+- Encoder changed to preserve type of numbers instead of chosing most compact encoding. The old
+  behavior can be achieved with Encoder.UseCompactEncoding.
+
+## v3.3
+
+- `msgpack:",inline"` tag is restored to force inlining structs.
+
+## v3.2
+
+- Decoding extension types returns pointer to the value instead of the value. Fixes #153
+
+## v3
+
+- gopkg.in is not supported any more. Update import path to github.com/vmihailenco/msgpack.
+- Msgpack maps are decoded into map[string]interface{} by default.
+- EncodeSliceLen is removed in favor of EncodeArrayLen. DecodeSliceLen is removed in favor of
+  DecodeArrayLen.
+- Embedded structs are automatically inlined where possible.
+- Time is encoded using extension as described in https://github.com/msgpack/msgpack/pull/209. Old
+  format is supported as well.
+- EncodeInt8/16/32/64 is replaced with EncodeInt. EncodeUint8/16/32/64 is replaced with EncodeUint.
+  There should be no performance differences.
+- DecodeInterface can now return int8/16/32 and uint8/16/32.
+- PeekCode returns codes.Code instead of byte.

+- [Extensions](https://pkg.go.dev/github.com/vmihailenco/msgpack/v5#example-RegisterExt) to encode

+- Renaming fields via `msgpack:"my_field_name"` and alias via `msgpack:"alias:another_name"`.
+- Omitting individual empty fields via `msgpack:",omitempty"` tag or all
+  [empty fields in a struct](https://pkg.go.dev/github.com/vmihailenco/msgpack/v5#example-Marshal-OmitEmpty).
+- [Map keys sorting](https://pkg.go.dev/github.com/vmihailenco/msgpack/v5#Encoder.SetSortMapKeys).
+- Encoding/decoding all

+  or
+  [individual structs](https://pkg.go.dev/github.com/vmihailenco/msgpack/v5#example-Marshal-AsArray).
+- [Encoder.SetCustomStructTag] with [Decoder.SetCustomStructTag] can turn msgpack into drop-in

+- Simple but very fast and efficient
+  [queries](https://pkg.go.dev/github.com/vmihailenco/msgpack/v5#example-Decoder.Query).

+
+## Installation
+
+msgpack supports 2 last Go versions and requires support for
+[Go modules](https://github.com/golang/go/wiki/Modules). So make sure to initialize a Go module:
+
+```shell
+go mod init github.com/my/repo
+```
+
+And then install msgpack/v5 (note _v5_ in the import; omitting it is a popular mistake):
+
+```shell
+go get github.com/vmihailenco/msgpack/v5
+```
+
+## Quickstart
+
+```go
+import "github.com/vmihailenco/msgpack/v5"
+
+func ExampleMarshal() {
+    type Item struct {
+        Foo string
+    }
+
+    b, err := msgpack.Marshal(&Item{Foo: "bar"})
+    if err != nil {
+        panic(err)
+    }
+
+    var item Item
+    err = msgpack.Unmarshal(b, &item)
+    if err != nil {
+        panic(err)
+    }
+    fmt.Println(item.Foo)
+    // Output: bar
+}
+```
